This small exhibition features a rare paper leaf from the 42-line Gutenberg Bible, which was printed by Johannes Gutenberg in the 1450s. The Gutenberg Bible was the first major book printed using mass-produced movable type and marked the start of the age of the printed book in the West. Forty-eight copies, or substantial portions of copies, survive and they are considered to be among the most valuable books in the world.

Despite the monumental nature of Gutenberg's discovery, his Bible is a conservative object designed to look like manuscript. It was even finished with hand rubrication, the practice of adding letters, usually red, to start a section.

Located in the lobby of the Howard Gotlieb Archival Research Center on the fifth floor of the Mugar Memorial Library. The exhibition can be viewed during regular office hours, Monday-Friday 9:00 AM -5:00 PM.
